112.PROJECT:Sheridan Big Goose Water Supply
SPONSOR:City of Sheridan
LOCATION:Sheridan County
PROGRAM:New Development
Purpose Chapter Session Account Appropriation Due Date
Level II 82 1998 I $75,000 2000
Level III 96 2000 I $1,587,000 2004
Level III 88 2002 I $297,000 2005

The water supply system for the Sheridan area is jointly operated by the Sheridan Area Water System Joint Powers Board (SAWSJPB) and the city of Sheridan. Water is diverted by the City of Sheridan and then conveyed to treatment facilities for the SAWSJPB and the City. During peak demand or when turbid water conditions exist the diversion and presedimentation facilities cannot meet the system demand. The level II study determined that expansion of the facility was required.

The WWDC contracted with MSE-HKM to conduct the Level II analysis. The Level II analysis recommended improvements and expansion of the existing diversion facilities from Big Goose Creek. The city was granted funding for these improvements during the 2000 Legislative Session.

HKM engineering of Sheridan was retained for design and construction engineering. Due to the complexity of the project, the initial cost estimates were found to be insufficient to allow the project to proceed to construction. The City requested additional funding in 2002 of $297,000 to cover the increase in the cost estimate.

This past summer the City of Sheridan proceeded to the bidding phase of this project. When the bids were received it again became apparent that the revised Engineering cost estimates exceeded the budget. The bids that were received were in excess of project funding by approximately $814,000. The City of Sheridan was able to temporarily provide enough money to award the bid. A change order was drafted, which removed several items from the construction contract until such a time that additional funding could be obtained to add the previously removed items back into the contract. The City of Sheridan is therefore requesting an additional $407,000 to cover 50% of the project overrun.

It is recommended that additional funding of $407,000 be approved for this project.
